1/16th comes out to .060 over, being .60 over is about the max usually....so id say not much more. but I'm no expert. ultrasonic testing would be needed of the bores.

then again a 55 block can be bored to a 374....can it go over 374...maybe... as I'm sure they did in 56 with oversize for the 374? I went from 352 to 374 on my 55 with stock 374 std pistons. no issues.
